Does MOSES Technology Enhance the Efficiency and Outcomes of Standard Holmium Laser Enucleation of the Prostate? Results of a Systematic Review and Meta-analysis of Comparative Studies.

Holmium laser enucleation of the prostate (HoLEP) is currently the size-independent gold standard for surgical treatment of benign prostate enlargement (BPE).

To systematically review the current literature and compare perioperative parameters, early outcomes, and complications after HoLEP with MOSES technology LEP (MoLEP) for BPE.

This study was performed according to the 2020 Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) framework using the PICOS (Patient, Intervention Comparison, Outcome, Study) model to frame the clinical question. The population was adults undergoing LEP for BPE, with standard HoLEP as the intervention and MoLEP as the comparison. The outcomes were enucleation time, surgical time, haemostasis time, energy used, hospital length of stay (LOS), recatheterisation, urethral stricture rate, and functional outcomes. The study type included randomised, prospective nonrandomised, and retrospective studies.

Seven studies were included for meta-analysis after screening. Mean enucleation time was significantly shorter for MoLEP (mean difference [MD] -7.27 min, 95% confidence interval [CI] -11.26 to -3.28; p = 0.0004). Postoperative LOS was significantly longer in the HoLEP group (MD 0.3 d, 95% CI -0.24-0.85,p<0.0001). Although not statistically significant, there was a trend for higher incidence of recatheterisation (odds ratio [OR] 1.39, 95% CI 0.47-4.09; p = 0.55) and urethral stricture (OR 1.81, 95% CI 0.45-7.37; p = 0.41) in the HoLEP group. The mean maximum peak flow favoured HoLEP (MD 0.95 ml/s, 95% CI -1.66 to 3.57; p = 0.47) and a lower mean postvoid residual volume was noted in the MoLEP group (MD -10.08 ml, 95% CI -53.54 to 33.37; p = 0.65).

MoLEP performed better in terms of intraoperative outcomes compared to standard HoLEP, resulting in shorter enucleation, haemostasis, and total surgical times for similar energy delivered. In addition, postoperative LOS with an early trial of catheter favours MoLEP, making it appealing as a day surgery procedure.

We reviewed the literature for early outcomes of laser treatment of the prostate for tissue removal using a MOSES system in comparison to standard treatment with a holmium laser for BPE. We found that the MOSES laser system can improve intraoperative performance, making prostate treatment a same-day discharge surgery.
